Kuvshinovo
At the confluence of the Negocha and Osuga stood the village of Kamennoye, recorded in a Rzhev district survey in 1624. The surrounding woodland and streams later supported a small paper manufactory. In 1799 the landowner Vasily Musin-Pushkin founded it near the village to make wrapping paper for sugar. Serfs worked the mill, turning rags and other fibres into paper, and the enterprise gave the old village a new occupation beyond farming and estate service.
